[0002] Switchgear, as a core piece of equipment in the power generation, transmission, and distribution links of a power system, directly impacts grid security due to its operational reliability. The switchgear's core component, the display, is used to monitor key parameters such as voltage, current, and temperature in real time, which is crucial for the normal operation of the power system. Therefore, the sensor status detection operation of the switchgear display is an indispensable part of ensuring the safe and stable operation of the power system. Through continuous monitoring of equipment status, damaged components can be replaced promptly, preventing small problems from escalating into major failures, thereby reducing maintenance costs. This is of great significance for ensuring the safe operation of power facilities, improving power supply reliability, and promoting the development of smart grids. Furthermore, accurate sensor status detection enables personnel to promptly identify potential problems, prevent faults, and avoid power outages and economic losses caused by switchgear malfunctions.

[0003] With the continuous upgrading of power equipment in recent years, switchgear has been widely used in substations of various voltage levels. Switchgear often has defects in the indicator function of the display module. Therefore, it is necessary to regularly test the display sensor status of the switchgear. However, the existing technology requires separate testing of the internal parts of the switchgear. Multiple devices need to be used for testing in sequence. When using this technology, maintenance personnel need to carry multiple maintenance devices and wiring harnesses. The testing is time-consuming and cannot take a fast and effective means to perform functional testing on the display module and sensors of the switchgear.

[0064] Power module 5 includes a high-voltage power module 51 and a low-voltage power module 52; both the high-voltage power module 51 and the low-voltage power module 52 are located inside the housing 1.

[0065] Relay 4 includes a display verification relay 41 and a sensor verification relay 42; both the display verification relay 41 and the sensor verification relay 42 are located inside the housing 1.

[0069] Low-voltage power terminal 126 and high-voltage power terminal 127 are respectively connected to power module 5;

[0070] The connection terminals, transmitter 3, display module 6, relay 4, power module 5, and sensor verification button 123 are electrically connected to form a switch cabinet sensor detection circuit;

[0073] In use, the switch cabinet sensor detection circuit is connected to sensor terminal 125, and the sensor of the switch cabinet under test is connected to the switch cabinet sensor detection circuit via a wire to sensor terminal 125.

[0074] The switch cabinet display module detection circuit is connected to the display terminal 124. The display module of the switch cabinet under test is connected to the switch cabinet display module detection circuit via a wire to the display terminal 124.

[0075] When in use, first take out several wires from the top cover 11 of the housing 1, then take out the corresponding power cord and connect it to the power interface 121 to turn on the power to the device. Then, according to the testing requirements, connect the sensor or display module of the switch cabinet under test to the interface corresponding to the connection terminal through the wires. At the same time, when needed, the power supply terminal can be connected to the switch cabinet under test through the wires. After the preparation is completed, press the sensor calibration button 123 or the display calibration button 122 to start the testing process with one click.

[0076] The display module 6 is used to display the operating status of the high-voltage circuit, providing real-time high-voltage information to help operators determine whether the equipment is energized. When testing the sensors of the switchgear under test, the switchgear sensor detection circuit uses the transmitter 3 to simulate and output a standard signal to drive the sensor under test. At the same time, the relay 4 is used to switch different operating parameters, which can quickly verify the sensitivity of the sensor and the stability of the signal transmission of the switchgear under test. During this process, the operating status of the sensor of the switchgear under test will be displayed through the display module 6, and the testing personnel can quickly and intuitively view the test results. Once an abnormality is detected, the sensor of the switchgear under test can be replaced in time.

[0077] When testing the display module of the switchgear under test, the switchgear display module detection circuit generates an analog signal through sensor 2 and inputs it into the display module of the switchgear under test. By observing the display module of the switchgear under test, the tester can compare the displayed value with the preset threshold in real time, thereby efficiently determining whether the display function is normal.

[0078] In summary, this invention integrates a switchgear sensor detection circuit and a switchgear display module detection circuit. Combined with the transmitter 3's analog output of standard signals, the relay 4's switching parameters, and the display module 6's real-time display of test results, it can quickly verify the functionality of the sensors in the switchgear under test and the display module within those sensors. Testing personnel only need to connect the wiring to the terminals and select the corresponding verification button to start the testing process with a single click, eliminating the need for separate testing of internal switchgear components. This significantly improves testing efficiency and reduces maintenance costs. Furthermore, the device can display the operating status of sensor 2 and the comparison values ​​on the display in real time, helping testing personnel quickly identify anomalies and promptly replace damaged components. This effectively prevents power outages and economic losses caused by switchgear failures, ensuring the safe and stable operation of the power system.

[0079] This invention optimizes the detection circuit by clearly classifying terminals, avoiding interference and facilitating power supply testing of the switchgear, thus reducing the false judgment rate. The grounding terminal 128 also improves the safety of the test, making the testing operation safer and more reliable. The top cover 11 optimizes wire management through a three-sided fixed mesh bag 111, preventing wires from scattering and tangling, improving portability and operational standardization.

The housing 1 is made of plastic, which reduces weight, lowers costs, and protects the internal modules. Overall improvements enhance the practicality, safety, durability, and user experience of the equipment, while optimizing space utilization and convenience, making the testing device more efficient and reliable.

[0081] Note: The above component brands, models / specifications can be adjusted and replaced according to the actual situation of the device, and are not considered as limiting conditions.

[0082] By connecting the sensor of the switch cabinet under test to the sensor terminal 125 of the device using wires, the sensor of the switch cabinet under test can be connected to the switch cabinet sensor detection circuit for detection.
